I have always gripped revolvers this way, from j frames to n frames. I recently took a chl class and the instructors didnt like it at first, but once they saw I was shooting ok with it they allowed it (best qual score in the class vs everyone else with semis, granted the qual was a joke). With the more traditional thumbs forward type grip I just feel too crowded on the grip, and feel like I dont get as much recoil absorbtion or trigger dexterity. In additon, I feel like my thumbs are doing more with the thumb wrap, vs just kind of floating uselessly in the thumbs tucked grip. Also my support pinky makes solid contact in the wrap vs hanging below grip in a traditional grip. Basically my support hand gets higher on the gun, which seems good. Does anyone else shoot like this even on large framed revolvers? I just feel like it's better for me in every way yet I rarely see it used aside from small revolvers. If there is a compelling reason why I should stop doing it, I will.
